The Anglin Lake trails in Great Blue Heron Provincial Park are in good condition having been groomed and track set Jan 25th after a 6 inch snowfall. The south side of the Spruce River Highlands Trail (Prince Albert National Park) to highway 263 parking lot, was packed by snowmobile the same day (photo-7) and is suitable for back country skiing, snowshoeing and fat biking. The north half of SRHT has about 8-10 inches of unpacked snow for the more adventurous.
